STEREOTYPERS CASTING MACHINE.

Application filed August 11, 1921. Serial No. 491,486.

To all whom it may concern:

Be it known that I, HARVEY L. FIsHER, a citizen of the United States, residing at Chicago, in the county of Cook andJState of Illinois, have invented certain new and useful Improvements in Stereotypers" Gasting Machines, of which the following is a specification.

My invention" relates to a stereotypers casting machine and more particularly to a machine having'a pair of spaced'platens against one of which the matrix is placed, being held thereagainst by suitable bars which also serve to confine the molten metal to the desired space between said platens.

In certain machines of this type as here-' tofore constructed one ofthe platens has been made stationary and the other movable relatively thereto consequently the metal confining bars which are carried by the movable platen ,chafe against the other platen when the movable platen is moved into and out of operative engagement with the other platen and after a casting has been made and as the movable platen is moved out of engagement with the other platen, the casting also chafes against the other or stationary platen. Obviously any chafing of metal against metal in a machine of this kind is very undesirable. In certain other machinesthe movable platen is moved into its approximate working position and is then'moved bodily manually against the stationary platen and secured thereagainst by clamping devices at the top and bottom which requires considerable time and labor; One of the objects of my invention, therefore, is toprovide a machine so constructed that both platens are movably mounted and are so arrangedthat the platensimaybe brought quickly and conveniently .into or out of operative engagement without any chafing of one platen against'the other, and without any chafing of the casting formed therebetween against either or said platens, and which will "require very few, if any, clamping devices to hold the two platens tightly together; I I x The invention in its preferred form contemplates a machine having a frame consisting of substantially vertical and horizontal portions; and a further object of my invention is to provide links for connecting the front and rear platens to the horizontal and vertical frame portions, respectively,

and'so arranged that the links'co-operate toform a toggle locking joint, the preferred arrangement being to connect the rear platen to the vertical frame portion byrelatively short links and to connect the front platen to the horizontal frame portion by relatively long links, which arrangement permits the front platen to have a range of movement sufficient to permit it to be swung from a substantially horizontal, or what may be termed a make-up, position over adjacent and into operative engagement with the substantially vertically positioned rear platen, the front platen when in its make-up position serving as a work table on which the matrix and the bars for confining the molten metal may be conveniently arranged.

A further object of my invention is to provide a machine in which one of the platens is adjustable relative to the other whereby the space between the two platens may be varied to form castings of different thicknesses, for example, a casting type high, or, a casting type high having a cored back, .or, a casting relatively thin in thlCk-f' ness commonly called a'skiver and which is-secured to a back ofwood of sufficient thickness to make high.

A further object of my invention isto the casting and back type r Fries; I

provide'means which will positively insure the two platens being brought intoor out of operatlve engagement simultaneously and which is preferably of such construction that no adjustments need be made even though one ofthe platens be adjusted relative to the other to vary the width of the space between said platens for the purpose aforesaid and in this connection myinvena tion contemplates the'provision of means,

preferably one or more springs, adapted to hold the rear platen up a distance above itsoperat'ive position, in combination with a pair of lugssecured at both sides to sa1d platens, the lugssecured to the front platen overlapping those-secured to the rear platen, whereby when the front platen is swung loo from itshorizo-ntal position to a position 40 I jpapier-mach flongs on the type'may be iii- {when the movable platen is swung into adjacent therear platen, the lugs carried 1 thereby will engage or bear down upon the lugs carried by the rear platen, consequently the front platen forcestherear platen down- Wardly simultaneously with it against the v tension of said springs and Without the occurrence of any, chafing action.

Ajfurther Object of the invention is to provide novel mean's'for clamping the upper portions of the two platens togetlierwhen they are in their operative position.

A further object of the invention is to provide a melting pot for the metal incom bination f-iwithi suitable means forv heating the same,which pot is so positioned and so mountedonthe frame of the machine that when it is tilted, thefmetal' will flow -there-' ings which are discarded.- This manner of preliminarily heating the platens involves useless labor and expense and'req uires'con siderable time. ,It is a,further, object oflmy invention "to provide WHIQZLIIS' for prelimi-.

s narily lieatingpthe; platen not carrying the desired temperature." w I a .In machinesiof'this type as constructed the bars for-confining the matrix which is of such: construction.that

thepla'ten. may 'be heated in a relatively short period of'timeland while the metal brought to the in the ainelting: pot: is being :A further object of ethetinvention.

' provide .meansjadapted .to preliminarily heat the platen not carrying-the matrix and wh ch'isf of such construction that the wet serted between" the platens and dried or baked to form'fthe'matrices, thus making it unnecessary *to provide separate or: special means for. baking the fiongs.

the platens have-{usually beenzloosely posit oned on the movahleplaten, consequently operative engagement =with the stationary or the other outlof parallelisnrwiththe consequent resultthattlie casting is not true,

Y the sides thereofhaving to be trimmed or shaved ofl' inorder to make -them true, before' it can be used'; and it is a furthe robjectof myinvent'ion toprovide novel means foi' attaching-the 'bottom an'd-side bars to one of the platens, preferably the front platen, which is of. such constructionsthat V the side 'bars'are positively maintained in parallel relationship and at the right angles to the bottom barpandiwhich also permits 'brokenoutp, r H

z ontal portion 15 mounted on suitable supportinglegs 16 and which is rigidly secured to, orintegrally forniedwith, an upstanding substantially vertical portion'lT Afi ont V platen 18*and'arear platen 19 are swing ingly connected to. the horizontal and vertical franieportions 15 and 17, respectively.

The front platen is pivotally connected at its bottom or rear endto a pair of links 20, the opposite ends of said links being pivotally connected to a pair of upstanding ears 21 formed integrally with and adjacent the front end of the horizontal frame portion 15.- The front platen is also pivotally connected to .a pair of links 22, the lower ends of which are pivotally connected to the frame portion 15, the links and 22 being relatively long and of such length that the front platen may be swung from a substantially horizontal position, as shown in Fig. 1, to a substantially vertical position, as shown in Fig. 3. A handle 18 is secured to the front platen to facilitate swinging the front platen from one position to the other.

The rear platen 19 is pivotally connected to a plurality of relatively short links 23 which are pivotally mounted on transversely extending bars 24 slidably mounted in horizontally extending slots 25 formed in the frame portion 17, see particularly Fig. 7.

' The bars 24: have threaded engagement with horizontally positioned threaded studs 26 each of which projects through a bushing member 27 threaded into the frame portion 17, the studs 26 having a collar 28' which bears against the inner end of the bushing members 27 to limit outward longitudinal movement of the stud. A. handle member 29 is secured to each of the studs to, facilitate rotation thereof. This arrangement permits the rear platen to be quickly .and conveniently moved toward or away from the front platen so that castings of different thicknesses may be made. The threaded portions of the studs 26 snugly engage the bars 24 so that when the desired adjustments have been made, no further attention need be given to this feature of the invention until it is desired to make a casting of a differerent thickness.

A pair of tension springs 30, see Figs. t and 5, the upper ends of which are secured to the vertical frame portion 17 and the lower ends of which are secured to the back of the rear platen 19, normally hold said platen upwardly in what, may be termed a preliminary position substantially as shown in Figs. 1 and 2. A pair of plates 31, see particularly Fig. 9, are secured to the bottom of the rear platen 19 adjacent its sides, each of said plates having a lug 31 which projects laterally somewhat beyond the sides of the platen. A pair of plates 32, similar to the plates 31, are secured to the bottom of the front platen 18 adjacent its sides each of which has a lug 32 also extending laterally somewhat beyond the sides of said platen. The lugs 32 are adapted to engage, or bear down upon, the respective lugs 31 of the plates 31 when the front, platen is brought into what may be termed its preliminary position as shown in dotted lines in Fig. 2. The co-engaging' lugs 31 and 32 being arranged at the side of the platens, do not interfere in any way with the adjustment of the rear platen to make castings of different thicknesses.

The links 20 and 22 connecting the front platen to the horizontal frame portion in cooperationwith the links 23 connecting the rear platen to the vertical frame portion form a togglearrangement for moving the platens into and out of operative engagement. Then the front platen is swung from its make-up position shown in full lines in Figs. 1 and 2 into its preliminary position shown in dotted lines in Fig; .2 the lugs 32 carried thereby bear down upon the lugs 31* carried by the rear platen. Movement of the front platen from its preliminary position to its casting position results in the rear platen being forced downwardly simultaneously with the front platen into its casting position and against the tension of the springs 30. As the front platen is moved upwardly from the position shown in Fig.3 the springs pull the rear platen upwardly simultaneously with the front platen until the rear platen reaches the limit of its upward travel which is the position shown in Figs. 1 and 2 and when that limit has been reached the front platen is in the position shown in dotted lines in Fig. 2, the distance between the adjacent lower most edges of the two platens being considerably greater than the thickness of the casting being made, consequently, there can be nochafing of the casting against the rear platen or of the metal confining bars, to be described presently, against the rear platen.

The links 20 and the lower pair of links 23 are in substantial alignment when the platens are in operative engagement and by proper adjustment of the bar carrying said links 23 the platens may be forced very tightly together at their lower ends without any additional clamping means. 22 and the upper pair of links 23 serve to force the upper ends of the platens together, but since these links are considerably out of alignment and because of the close engagement of the platens at their lower ends, there is a tendency for the platens to spring apart slightly at their upper ends. I preferably provide means, therefore, to insure a tight fit of the platens at their upper ends, which means preferably consists in a pair of clamping members 33 one end of each of said members being pivotally connected to a member 34 swivelly mounted on the sides of the, rear platen, the swinging ends of the members 33 being threaded and adapted to slip into engagement with the respective notched members 35 secured to the front platen. A handle portion 36 is threaded on each of the members 33. \Vhen The links the platens are in their open position, the

handle members 33 are free to swing downwardly substantially. as shown in Figs. 1'

and 2 Where they are out of the way. When the platens are moved into operative engageof the :two platens tightly together.

r .In order to limit outward swinging movement of the front platen I provide a rod 37 pivotally connected'at its upper end to the platenpthe lower end of which slidably proje'cts through a member 38' pivoted on a forwardly extending arm 39 formed integrally withthe frame portion 15, a collar 40 being fixed to the lower endiof the rod 37 to limit upward movement. thereof through tliemember 38.. If desired, a spring 4l' may be: provided on the rod 37 between the platen and the member 38 which, it will be noted, will beconsi-de'rably compressed when the front platen is in its vertical position and will assist in movingsaid platen from said position into its horizontal position.

A melting pot 42 'for'the stereo-metal is pivotally mounted between a pair of brackets 43 secured to the upper end of the frame portion'17. The melting pot is provided with a'pouring spout '42 so that when the-pot is tilted into the position shown in FigI-3, the molten metal. will flow therefrom into the space between the two platens, the pot being provided with a handle member 44 to facilitate tilting it. A burner 45, see Figsi4 and 5, of any desiredconstruction, is: positioned underneath the melting pot receiving its fuel from a pipe 46 controlled by a'valve 47, the pipe 46 being connected with a header 48 which receives fuel from any convenient source. The back of the upper end of the frame portion 17 serves to direct the flames from the burner 45 upwardly against the forward side of the melting pot and a housing member 49 seoured to said frame portion serves to dii'eot the fiames upwardly againstvthe rearward side of t'he melting pot. By this arrangement a pot of cold metal may be brought tothe desired-fluid state in a very short period of time. preferably provide means for preliminarily heating both the front and rear sides of therear platen, and for this purpose a burner 50 is positioned preferably directly 7 'underthe space between'the front and rear 'nected with thel'pipe "48.

platens which is supplied with fuel by a pipe 51 controlled by a valve 52 and'con- A burner" 53' is positioned under the rear platen'receiving its fuel from a pipe 54"ccntrolled by a valve 55 andconnected'with the, pipe 48. The

ing each provided with a plurality of apertures 19 so that the heated currents of air from the burners 50 and 53, particularly from the burner '53, will pass upwardly therethrough. A sheet metal plate 56 is se-' cured: to the sides of the rear platen an said ribs and said plate. 7 This arrangement provides a flue in the rear platen through which the currents of heated air pass whereby the rear platen may be heated to the proper temperature while-the stereo-metal is being heated. With an arrangement as abovedescribe'd it is not necessary to-provide any separate or additional means for baking the wet papier-imach flongs as is customarily done with machines of this typ as heretofore constructed. I

The means for confining the molten metal to the desired space between the platens is best shown in Figs. 8, 10 and 11 and includes a transversely extending bottom bar 58, which is adapted to be positioned against the lugs 32" projecting from the plates 32 secured to the front platen, and sidebars 59 and 60. The side bar 59 at its rear end is provided "with a depending tongue 61 which engages a bracket member 62-secured to the side of the platen,'see Fig. l0, and at its forward'end' i-sprovided with a. de pending. tongue 63 which is adapted to engage abracket member 64 also secured to the side of said platen. The rear or. bottom end ofthe bar 59 fits snugly into a recess 65 formed in the adjacent side of. the bar 58, see Fig; 8, and that end of the bar 59 is provided with a kerf 66 adapted to receive a laterally projecting tongue 67 formed on an angle member 68 which is securedby screws 69 to the bar 58. The tongue 63 is bevelled off at 63 and comesinto snug engagement withthe bracket 64,"when thebar 59 is flat'against'the platen, in whichposition the rear orbottom end of the bar 59 is forced into the bottom of the recess 65 and the bar 58 is pushed firmly against'the lugs 32; The bar 58 is preferably recessed to recei'vetongues 32* formed on: the lugs '32 to prevent longitudinal movement of the bar. the bars 58 and 59 are in the position shown in Figs. .8 and 10 they are rigidly secured togetherand to "the platen, and that the bar 59 may be raised or positioned obliquely relative to the platen, which, of course, re-

sults in tilting or rocking the bar 58 on its rear bottom longitudinally extending edge, without disengaging it from the bar 58. If

desired, a screw 7 O'may be used for securing 130 thebar'59 to the angle iron'68;

It will thus be apparent that when d to therear ends ofthe ribs 19*, an asbestos lining 57 being preferably interposed betwe The bar 60 is maintained in parallel relationship with the bar 59 preferably by a toggle mechanism comprising a pair of links 71, each being pivotally connectedatone end to angle members 7 2, which are pivotally connected to bracket members 73 secured to the side of the platen, and at the other end to the adjacent ends of the respective links 74 and to the extremities of 'a bar 75 in parallel relationship withthebar 60. 'One flange of an angle member 76 is secured to the side of the bar .60, the adjacent ends of the links '74 being pivotally connected to the other flange'of said anglemember. It will be apparent that thisarrangement permits the bar 60 to be moved away from or toward the bar 59 thereby readily accom modating matrices of diiferentwidths. The bars 59 and 60 are at all times in parallel relationship and secured at right angles to the bar 58. The casting'formed in themes chine is absolutely true and smooth on each side and on. its rear or bottom end, it being i unnecessary to shave or trim otf its sides and said end before using it. A matrix 7 7 of any desired width may be easily inserted in place on the platen by shifting the bar; 60 away from the bar 59 and then raising obliquely the bars 59 and 58 and slipping the matrix under the bars 59 and 58. The bar (iOmay then be swung upwardly away from the plat-en and pulled over toward the bar 59 the required distance and positioned over the adjacent edge of the matrix.

In preparing to dry or bake the wet papier-mach flongs the bar 58 is removed, only the bars 59 and 60 being used to confine the heat between the platens. When the bar 58 is removed, the space-between the; bars 59 and 60 and the two platens forms a flue which is directly over the burner 50.

lVhen it is desired to make a casting type high with a cored back, I securea core member 78, see Figs. 11 and 12, to the face of the rear platen by a plurality of screws 79, the core "member having a plurality of vertically extending ribs80 and grooves 81. A. transversely extending bar 82 is secured to the rear platen by screws 83 under the core member 78, the front side of said bar being flush with the front side of the ribs 80. Vhen making castings of'this type, the

bar 58 is removed and a thinner bar 58 is substituted therefor. the angle member 76 are also removed and I an angle member or bar 84;, substantially of The side bar 60 and the cross section shown in Fig. 11, is substituted therefor, one flange thereof being adapted to extend into any one of the grooves 81 of the core member and thoother, I

flange thereof being pivotally' connected to the adjacentendsof the links/74' of the toggle mechanism for maintaining-"the member 84 in parallel relationshi p with the bar 59. In Fig. 11 the bar 84 is shown in position to make a casting two columns wide: It. will be obvious, however, thatthe bar 84 may be positioned in any of the grooves 81 so thatcastings of different widths may be made. It will be apparent when the platens going description that a relativelythin casting, for example, a skiver may be made by moving the rear platen the desired distance toward the front platen; and by substituting in place of the bars 58, 59 and 60, relative thin bars for confining the metal, the principles of operation being precisely the same.

I do not intend to. limit my invention to" the details of construction shown and described herein, except only in so far as certain of the appended claims are specifically so limited, as it will be obvious that various modifications may be made by those skilled in the art without departing from the principles of the invention.
